BioTechUSA Magnesium Chelate 60 Caps

Magnesium supplements are not interchangeable, and the difference is not the milligrams on the front of the bottle. It is which form of magnesium those milligrams are bound to, because that decides how much of it you actually absorb.

The cheap option is magnesium oxide, which is poorly absorbed and well known for upsetting the stomach. BioTechUSA use magnesium bisglycinate instead - magnesium bound to the amino acid glycine, a chelated form that is absorbed far more readily and sits gently enough to take before bed. Magnesium contributes to normal muscle function, normal energy-yielding metabolism and the reduction of tiredness and fatigue, all of which matter more when you are training hard and losing minerals through sweat.

The bottle holds 60 Capsules taken one a day, giving 60 servings - two full months.
